Method Detail

getAdaptableInterval

public static AdaptableInterval getAdaptableInterval(TopocentricFrame topo,
                                                     double elevationSwitch,
                                                     double fineCheckInterval)

Method providing a candidate AdaptableInterval for arbitrary elevation detection with forward propagation. It uses a Keplerian, eccentric approximation.

Parameters:

topo - topocentric frame centered at ground interest point

elevationSwitch - elevation above which interval will switch to fineCheckInterval (typically DEFAULT_ELEVATION_SWITCH which is -5°)

fineCheckInterval - check interval to use when elevation is above elevationSwitch

Returns:

adaptable interval for detection of elevation with respect to topo
